2005 Mercedes-Benz SL500 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2005 Mercedes-Benz SL500

The active body control system can leak fluid from numerous areas, including the tandem pump, hydraulic lines, struts, and/or seals. If it is not repaired, the vehicle ride height could drop too low and cause damage to the undercarriage.

The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

Leaks may develop from the differential cover and/or seals on high mileage or older vehicles. Our technicians recommend a complete reseal of the differential unit if these leaks are addressed.

Due to deterioration of the wiring harness connection or failure of the hydraulic pump, the sensotronic brake control (SBC) system may default to the hydraulic back-up mode. In the back-up mode, the driver has braking power sufficient to stop the vehicle, but greater brake pedal pressure is required and brake pedal travel will be noticeably longer.

The Mercedes-Benz recall numbers are 2005070007 AND 2005110001.
